This is useful for example on the eeePC 701, where the EDID/DDC lines
from the LCD display are not wired to the video card as expected (I
confirmed this by downloading the eeePC schematics, the LCD is somehow
wired to what would normally be a PS/2 port on the embedded controller).
In this case, there is no way we can get the EDID data from the usual
means, however, we still know the panel resolution by looking it up in
the VESA BIOS, and if we found it there, there has to be an LVDS panel,
so we can configure it.
Should fix#14066.
